shown on Exhibit L Sampling frequenry for water
levels and water quality was 3 times per year.
as AppendQ L Minimum and maximum compari-
sons are presented in Appendu E
Monitored parameters included water level, pH,
conductivity, temperature, total dissolved solids,
total suspended solids, total iron, and total manga-
nese. Results of the sampling efforts are surntna-
rized in Appendix H. Hydrographs depicting water
levels from 1978 to the present have been included
Water level and sampling records for water year
1991 were complete for ten wells. Water in 11
wells was either nonexistent or insufficient for
sampling. Neither water level or quality samples
were acquired fiom wells SOM-38-H2 and SOM-
38-H3. Casings of these wells were damaged before
